We are familiar with massless radiation emitted from black holes via Hawking radiation. A similar effect is seen by atoms falling into a black hole, emitting acceleration radiation that looks like Hawking radiation, but is different. The entropy of this radiation, called horizon brightened acceleration radiation (HBAR), is investigated using laser-like analysis. We gain useful insights about the equivalence principle between acceleration and gravity.

Star Forming Cores and Recent Unexpected Findings from the Atacama Large Millimetre/Submillimetre Array

The formation of stars occurs in incredibly large clouds of gas. This gas condenses and a core is formed in the cloud. Once this denser cloud is sufficiently large enough the gas collapses further and forms a star or a handful of stars. One would expect that the size of the core would dictate the size of star or stars that are formed from the core. Indeed, observations of star forming regions close to our solar system support this relation. The “Initial Mass Function (IMF) and the “Core Mass Function (CMF)” seem to be related. However, recent findings from the Atacama Large Millimetre/Submillimetre Array are challenging this understanding. This presentation will cover concepts surrounding this topic and discuss these recent findings.
